All information coming to person consists of signals. It is known that such signals a person gets much more than able to treat his brain. In addition, a person is so arranged that he:

• can not perceive incomprehensible information to him;
• it is impertient, that is, it often perceives the information not as it is, and what it seems to him;
• quickly get tired and can be wrong, processing information;
• could not store information for a long time: if you do not fix knowledge with permanent exercises, the information is very quickly forgotten.

Credit with these problems a computer helps a computer. He facilitates the mental work of a person helps to cope with the gigantic volumes of information.

Today, the computer is an indispensable man's assistant in any field of activity. Without computers, it is impossible to imagine the work of banks, shops, hospitals, schools, other institutions. Without computers, it is not necessary to prepare for the publication of books and magazines, in scientific and engineering calculations, when creating special effects in movies and on television and in many other cases. With the help of a computer, a person can draw, listen to melodies, watch cartoons and do much more.

In a single collection of digital educational resources (SC.edu.ru), the animation "Computer, his role in a person's life" is posted. It will allow you to compare the tasks solved with the help of computers a few decades ago and today.

The object suitable for many purposes performing a variety of functions is called universal.

The most diverse information presented in the form suitable for computer processing is called data. For a short time, the computer is able to process a large number of data.

The computer processes data on specified programs.

Unlike a person, the computer can not think. He performs only what he is prescribed. Often talk about computer errors, but, as a rule, these are the mistakes of people who have developed incorrect programs for the computer.

How the computer is arranged

The main computer is a system unit that includes the processor, devices random access memory (Memory Chips), Hard Drive, Power Supply, etc. (Fig. 2).

Fig. 2.

You can look inside the system unit using an interactive resource "components of the system unit", placed in a single collection of digital educational resources (SC.edu.ru). The processor is designed to handle data and managing the work of the computer.

The computer memory serves to store data and is divided into operational and long-term.

All programs and data required for the computer are placed in RAM. The processor can instantly access information in RAM. After turning off the power supply, all the information contained in RAM is lost.

For long-term storage of information, a hard disk is used - a long-term memory device.

For more information about the hard disk and other devices of long-term memory, read in an electronic application to the textbook.

The keyboard is used to enter information into the computer's memory.

The monitor is designed to display information on the screen or, also say, to display information on the screen.

The mouse is one of the main input devices intended for computer management.

Additional devices can be connected to a personal computer:

• joystick (to control the computer during the game);
• scanner (for input graphic images in the memory of the computer directly from the paper original);
• microphone (for input audio information);
• printer (to display information on paper);
• acoustic speakers or headphones (for output sound information).

There are other devices. All of them make up computer hardware.

Remember appearance and names computer devices You will be helped by the game "Couples" from an electronic application to the textbook.

Safety and organization of the workplace

Remember! Dangerous voltage is lifted to each workplace.

While working should be extremely attentive.

In order to avoid accidents, defeat electric shock, equipment breakdowns are recommended to follow the following rules:

• Come in the computer class calmly, not hurry, not pursuing, not hurt furniture and equipment, and only with the permission of the teacher.
• Do not turn on and do not turn off the computers without the permission of the teacher.
• Do not touch the electrical wires and connecting cable connectors.
• Do not touch the screen and back of the monitor.
• Do not place outsiders in the workplace.
• Do not get up from your places when visitors come to the office.
• Do not attempt to independently eliminate malfunctions in the work of the equipment; In case of failures and failures in the computer, immediately stop working and report this to the teacher.
• Work on the keyboard clean, dry hands; Easily press the keys, without allowing sharp blows and without holding down the keys in the pressed position.

Remember! If you do not take precautions, work at the computer may be harmful to health.

In order not to harm your health, you need to follow a number of simple recommendations:

• Incorrect landing at a computer can cause pain in the shoulders and lower back. Therefore, sit free, without tension, without stitching, not leaning and not bothering on the back of the chair. Put the legs directly to the floor, one near the other, do not pull them out and do not be pumped (Fig. 3).

Fig. 3.

• If the chair allows you to adjust the height, it should be adjusted so that the angle between the shoulder and forearm was slightly more direct. The body must be from the table at a distance of 15-16 cm. The line of the gauge should be sent to the center of the screen. If you have glasses for constant wearing, work in glasses.
• Shoulders when working should be relaxed, elbows - slightly touching the body. The forearms should be at the same height as the keyboard.
• With stressful long-term work, the eyes are overwhelmed, so every 5 minutes, take a look from the screen and look at something far away.

The most important thing

The science of informatics is engaged in learning all sorts of ways to transfer, storing and processing information. Store, process and transmit information to a person helps a computer - a universal machine for working with information.

The computer hardware is distinguished by entering, processing, storing and output information. Information entry devices are keyboard, mouse, scanner, microphone, etc. Information processing device is a processor. Information storage devices - RAM, external memory on hard drives.

How the computer is arranged

The main thing in the computer is a system unit, which includes the processor, memory, drives on rigid and magnetic disks, power supply, etc.

The processor is intended for computing, processing information and management of computer work.

Computer memory serves to store data. There are two types of memory: operational and constant. Devices that implement them are called RAM and ROM. The ROM stores the instructions that determine the operation of the computer on. These instructions are not deleted even when the computer turns off. All programs and data required for computer work are placed in RAM. After disconnecting the computer, all the information contained in the RAM is deleted. RAM board constant storage device

For long storage of information is used long term memory: Magnetic discs, optical discs, other devices. Magnetic discs are rigid and flexible. Hard drives large capacity Embed into the system unit and are constantly there. In the system unit there are flexible drives magnetic disks - floppy disk. Unlike flexible, hard drives cannot be transferred. Recently, more spread received optical discs, flash drives.

To enter information in the computer's memory, the following devices are applied: The keyboard scanner to display information in the computer's memory applies the following devices: Monitor Printer

Additional devices: Mouse Acoustic Speakers Joystick Others All make up the computer hardware to perform the hardware test:

3. Theoretical part.

Computer is a universal machine for working with information. The information presented in the form suitable for storing, transmitting and processing with a computer is called data.

The science of informatics is engaged in learning all sorts of ways to transfer, storing and processing information.

Sometimes they say "Personal Computer". The clarification of the "personal" here is not by chance - this means its own, personal, accessible to most people, because there are a large number of other types of computers that do not name personal - workstations for enterprises, servers for connecting multiple computers to the network and others. In the future Speaking "Computer" We will keep in mind exactly a personal computer.

Personal Computer - This is a computer designed to serve one worker. In its characteristics, it may differ from large computers, but it is functionally able to perform similar operations. Computer is a universal machine for working with information.The information presented in the form suitable for storing, transmitting and processing with a computer is called data.

PC basic configuration - minimal set hardwaresufficient to start working with a computer. Currently, a configuration is considered for desktop PCs, which includes four devices:

System unit;

Monitor;

Keyboard;

Mouse.

The system unit is the main block of the computer system. It contains devices that are considered internal. Devices connected to the system unit outside are considered external.

The system unit includes a processor, RAM, drives on rigid and flexible magnetic disks, on optical disks and some other devices. On the front panel, you see a few buttons - the Power button already known to you - the RESET button is rebooting the computer, which can be used only with the permission of the teacher. Several light indicators - inclusion and access to the hard disk. Two drives - for CDs and disks, talking about the next lesson.

Monitor - device for visual playback of symbolic and graphic information. Serves as an output device. They remotely resemble household TVs.

IN desk computers Usually used monitors on an electron beam tube (CRT). The image on the monitor screen is created by a bunch of electrons emitted by an electron cannon. This electron beam accelerates high electrical voltage (tens of kilovolt) and falls on the inner surface of the screen, coated with a phosphor (substance glowing under the influence of the electron beam).

A bundled control system causes to run it line by the entire screen (creates a raster), and also adjusts its intensity (respectively, the brightness of the luminofor point luminescence). The user sees the image on the monitor screen, since the phosphor radiates light rays in the visible part of the spectrum. The image quality is higher than the smaller the size of the image point (luminofor point), in high quality monitors, the point size is 0.22 mm.

However, the monitor is also a source of high static electric potential, electromagnetic and X-ray radiation, which can adversely affect human health. Modern monitors are almost safe, as they correspond to rigid sanitary and hygienic requirements.

Flat monitors on liquid crystals (LCD) are used in portable and pocket computers. Recently, such monitors have become widely used in desktop computers.

LCD (Liquid Crystal Display, LCD monitors) are made of a substance that is in a liquid state, but at the same time has some properties inherent in crystalline bodies. In fact, these are fluids with anisotropy properties (in particular, optical) associated with ordering in the orientation of molecules. Liquid crystal molecules under the influence electric voltage These orientation can change and as a result of this, change the properties of the light beam passing through them.
The advantage of LCD monitors in front of the monitors on the CRT is the absence of electromagnetic emissions harmful to humans and compactness. But LCD monitors have both disadvantages. The most important of them are bad color reproduction and lubrication of a fast moving picture. In other words, if you take a fairly high-quality electrical monitor, it will be suitable for any tasks without reservations - to work with the text, for processing photos, for games, and so on; At the same time, among the LCD monitors, you can select models suitable for games - but they are not suitable for working with photos, you can highlight models that have excellent color reproduction - but they are poorly suitable for dynamic games, and so on.

Monitors can have a different screen size. The size of the screen diagonal is measured in inches (1 inch \u003d 2.54 cm) and is usually 15, 17, 19 or more inches.

Keyboard - keyboard device designed to control the operation of the computer and enter information into it. Information is entered in the form of alphanumeric symbolic data. The standard keyboard has 104 keys and 3 informing about the operating modes of the light indicator in the upper right corner.

Mouse - a "graphic" control device.

When moving the mouse on the mat on the screen, the mouse pointer is moved, with which you can specify objects and / or choose them. Using the mouse keys (there may be two or three), you can set one or another type of operation with an object. And with the help of the wheel, you can scroll up or down without fit on the screen, text or web pages.

In optical-mechanical mice, the main working body is a massive ball (metallic, coated rubber). When moving the mouse over the surface, it rotates, the rotation is transmitted by two shafts, the position of which is read by infrared optopters (i.e., pairs "light emission-photodetector") and then converting into an electrical signal, controlling the mouse pointer movement on the monitor screen. The main "enemy" of such a mouse is pollution.

Currently, optical mice received widespread, in which there are no mechanical parts. The light source located inside the mouse illuminates the surface, and reflected the light is fixed with the photodetector and is converted to moving the cursor on the screen.
Modern models of mice can be wireless, i.e. Connecting to a computer without cable.

Peripherals call devices connected to a computer from outside. Usually these devices are designed to enter and output information.

Here are some of them: printer, scanner, modem, DVB card and satellite antenna, Web-camera.

The printer is used to display information on a paper carrier (paper).
There are three types of printers: matrix, inkjet, laser.

Matrix printers are shock action printers. The print head of the matrix printer consists of a vertical column of small rods (usually 9 or 24), which under the influence of the magnetic field "pushed" from the head and hit on paper (through the painting tape). Moving, the print head leaves the string of characters on paper.

The disadvantages of matrix printers are that they are printed slowly, produce a lot of noise and print quality leaves much to be desired (corresponds to about the quality of the typewriter).

In recent years, black and white and colored inkjet printers have been widespread. They use the ink print head, which under pressure throws ink from a number of smallest holes on paper. Navigating along the paper, the print head leaves the string of characters or striped image.

Inkjet printers can print enough (up to several pages per minute) and there are little noise. The quality of printing (including color) is determined by the resolution inkjet printerswhich can achieve photographic quality 2400 dpi. This means that the image strip horizontally 1 inch long is generated from 2400 points (ink droplets).

Laser printers provide almost silent printing. High print speed (up to 30 pages per minute) Laser printers are achieved by post-page printing, at which the page is printed immediately.

High typographical print quality laser printers Provided by high resolution, which can reach 1200 DPI and more.

Plotter. For the withdrawal of complex and widescreen graphic objects (posters, drawings, electrical and electronic circuits And pr.) Special output devices are used - plotters. The principle of action of the plotter is the same as the inkjet printer.

Scanners serve to automatically enter texts and graphics to the computer.

Scanners are two types: manual, tablet.

A manual scanner for a computer is similar to the scanner used in supermarkets for reading the barcode. Such a scanner moves along a sheet with information line by manually, and the information is entered into the computer for further editing. The tablet scanner looks and works in about the same way as xerox - the cover is lifted, the text or the picture is placed on the working field, and the information is read. Tablet scanners in our time are usually all color.

Recognition systems text information allow you to convert scanned text from graphic format to text.

The resolution of the scanners is 600 dpi and above.

The modem or modem board serves to communicate remote computers by telephone network. The modem is internal (installed inside the system unit) and external (located near system block and connects with it using a cable.

DVB card and satellite antenna serve for the so-called "asynchronous" computer connection to the Internet. If there is a DVB card and satellite antenna For connecting to the Internet, two communication channels are used: a modem is used to receive data from the user, and for receiving satellite canal, the flow rate in which is several times the modem.

For the organization on endless Internet video conferencing (or just chatter), a webcam is useful. With the help of these devices (and, naturally, quick local networks), You can at any time arrange a meeting with your employees, without opening it from agenic jobs. And this, as practice shows, gives a very tangible practical benefit.

Let's notify immediately - about the real camcorders here does not go. That is, you may not even dream of good optics, about high-quality color reproduction and the like of luxury. Yes, and keep the video from the webcam you will not come to mind. After all, this unit is needed completely for another - to provide an admission to your computer video stream with quality and volume sufficient to transfer on the Internet.

Here, however, there is one quarrel. Almost all webcams are designed to work by no means in slow mode of modem connection. Submit them digital Channels Communications - And then, these devices will show themselves in all its glory.

As for Russia, the ability to ensure the transfer of such data flow in real time, alas, until not. Neither in transmitting devices, no communication channels. Therefore, the maximum that your interlocutor can count on - this is the appearance of your personality in a tiny window of a slightly smaller cigarette pack (the image size is up to 320x200 points). If this is enough for you, well, the purchase of a webcam can slightly brighten up your gray computer weekdays.

Since the image of the webcam displays not static, you need to consider another important value - the framework of refreshments.

So, on the usual, modem connection Even with a tiny picture of 150x200 points of the desired 24 frames, you will most likely not get (real - from 10 to 20). So, jerks and delays are inevitable ... However, do not be mistaken - alternative methods Connections with the Internet still stubbornly pierce their way and, perhaps, after a year, your vesati will be able to enjoy decent quality by the image of at least a quarter of the screen.

For the fact, pay attention to other webcam indicators - the reaction to various lighting conditions, the presence of a built-in or additional microphone, the length of the connecting USB cord, the camera's ability to work "in a bundle" with popular programs for voice and video relationships (for example, Microsoft NetMeeting). And, of course, on maximum resolution: Although the picture quality of 640x480 points has long been the standard, there are models on the market with a much lower resolution threshold (many cameras cost up to $ 50 provide permission only to 352x288 points).

By the way, do you know that a good webcam can be successfully replaced by a digital camera? Most cameras can not only transmit a stream of video information on the computer, but also pull out individual frames and pictures from this stream. But their future fate depends on the quality of the camera: expensive models can save images in the built-in memory, without requiring a constant connection to the computer, more cheaply forced to immediately discharge all their "cargo" to a hard disk.

Although, of course, the real digital camera works much better, and the quality gives the other ... especially since many digital medium price categories can also, if necessary, work and webcams.

And last. Almost all camera models released after 1999 are connected to the computer through the USB connector and do not require an additional power source.
